DRESS-FORM. I

To all whom itmay concern:

Be it known that I, JAMES M. VANDnR- GRIFT, a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented an Improvement in Dress-Forms, of which the following description, in connectionwith the accompanying drawing, is a specificatlon, like characters on the drawing representing like parts.

This invention is an improved dress form support of that type in which an extensible Standard is made in sections telescoping one within the other to permit the form to be raised and lowered. I

The object of the invention is to provlde a novel clamping device for clamping the standard sections in any adjusted position relative to each other.

i In order to give an understanding of the invention Ihave illustrated in the drawlngs a selected embodiment thereof which will now be described, after which the novel features will be pointed outin the appended claims.

Figure 1 of the drawings is a view of a dress form having my improvements applied thereto;

Fig. 2 is an enlarged vertical sectlon through the clamp;

Fig. 3 is a section on the line 3-3, Flg. 2.

1 indicates a dress form body which may have any suitable or usual construction. It

is shown as supported on a standard comprising the two sections2 and 3 wh ch have a telescopic relation, the upper sectlon 2 to which the dress form is secured telescoping within the lower section 3, and the latter being secured to a pedestal or base 4, as usual in dress forms.

My improved clamp or clutch for holdlng the upper section of the dress form at any adjusted height comprises a clutch member 5 sustained by the lower section 3 and having an aperture 6 through which the upper section 2 extends, said clutchmember being normally held at a slight inclination so that the opposite edges 7 of the apertures 6 will be operated from any convenient point. As

Patented Aug. 7, 191a.

herein illustrated the lower section 3 of the standard has a collar 8 fast thereto at its upper end and secured to the collar 8 is a bracket 9 having the overhanging portion 10 provided with an aperture through which the upper standard section 2 extends. clutch member 5 is formed with the down- The turned flange 11 which ismovably secured I to the bracket 9 by means of bolts 12. Each bolt has a spring 13 encircling it which is action of the springs 13 is to tend to turn the clutch member into its inclined locking po-' sition. The overhanging portion 10 of the bracket is provided with a pair of depending arms 14111 which is pivoted a releasing cam 15 that is adapted to engage the outer edge of the clutch member 5. When the releasing cam is turned, it will act against the end of the clutch member 5, thereby rocking or swinging the same into a position at right angles to the axis of the standard and thus releasing the clutching engagement between said member and the upperstandard section 2. This movement of the clutch member is against the action of the springs 13. When the releasingcam is itself released, the springs 13 act automatically 'to bring the clutch member 5 into its operative clutching position. The releasing cam 15 may be op: erated in any suitable way. As illustrating one convenient construction, I have shown a treadle 16 which is pivotally connected to the standard at 17 and'which-is connected by a rod 18 to said cam 15. The connection limited to this form of device. 19 isa spring -is such that a downward movement of the acting on'the pedal and tending to raise it and thereby move the releasing cam into its inoperative position.

The operation of adjusting the height of the dress form involves merely depressing the pedal'thereby actuating the releasing cam 15, and releasing the clutch member 5 from its clutching engagement withthe upper'section 2. The upper section is then free to be moved up and down as desired, and as soon as the proper adjustment'has been made, the pressure on the treadle may be removed. The springs 13 act automatically to throw the clutch into its operative clutching position, thereby firmlvlocking the up; l

per standard section 2 in its adjusted position.

I claim: f I 1. A dress form support 1nc1udmg a supporting standard comprising two sectlons aving telescopic relation, aclutch member carried by one section and provided with an aperture through which the other section extends, a spring acting on said clutch member and tending to hold it in such an angular position relative to said other standard section that said section 1s grlpped by opposite edges of the aperture in the clutch member, and a clutch-releasing cam by which the clutch member is released fromclutching engagement with the standard section. a

2. A dress form support including a supporting standard comprising two sections having telescopic relation, abracket carried by the upper end of the lower section, a

clutch member sustained by said bracketand provided with an aperture through which the upper standard section extends, a spring acting on the clutch member 'and tending to swing it vinto an angular'position relative to said upper standard section thereby to bring the opposite edges of said aperture into clutching engagement 'wlth said standard section, a clutch-releasing cam pivoted to said bracket, and means for actuating said cam to release the clutch from clutching engagement with the standard sections. Y

"3. A dress form support, including a supporting standard comprising two sections having telescopic relation, a bracket carried by one end of the outer section, a clutch member having two flanges at an angleto each other, one 013 said flanges having a part adapted and positioned to engage with the side of the inner standard section and the other of said flanges being disposed adj acent to a surface of-said bracket, a spring normally tending to press said last mentioned flange said bracket togetherand move said firstmentioned flange into gripmember against the action of said spring to release said inner standard-section.

4. In combination, two telescopic members, a bracket carriedby the outer member,

a clutch member carried by said bracket and having two flanges at an angle to each other, one of said flanges having an aperture through which the inner member extends, and a spring normally acting upon the other flange and tending to swing the apertured flange to a position at an angle to the general direction of said telescopic members.

5. In combination, two telescopic members, a bracket carried by the outer member,

a clutch member carried by said bracket and having two flanges at an angle to each other,

' ping engagement with said inn'er standard 1- sect on, and means for tilting said clutch one of said flanges having an aperture through which the inner member extends, a spring normally actin upon the other flange and tending to swing the apertured flange to a position at an angle to the general direction of said telescopic members,

and a lever (pivoted to said bracket and having one en adapted toengage with said apertured flange to swing it against the action of said spring.

6. In combinat1on, two telescopic members, an apertured clutch member carried by the outer member and mounted to swing about an axis at one side of the-inner mem- JAMES VANDERGRIFT.
